Thaum lawv lub zog tensile yog kwv yees li qub,titanium alloysmuaj kev ua tau zoo tshaj plaws tag nrho. Qhov no tsis yog vim lawv qhov "nyuaj," tab sis vim tias lawv hnav, muaj lub zog siab, thiab tiv taus corrosion thiab crushing.
Titanium alloys ua haujlwm zoo dua stainless hlau hauv txhua yam ntawm kev ua tau zoo, tab sis tus nqi yuav tsum raug ntsuas. Cov xwm txheej uas titanium alloys nyiam muaj xws li huab cua ib puag ncig, kev xav tau hnyav, thiab ntev - lub sij hawm corrosion kuj.
Titanium alloy bolts outperform stainless hlau bolts hauv lub zog, corrosion kuj, thiab lub teeb yuag, tab sis kim dua. Cov ncauj lus kom ntxaws kev sib piv thiab cov xwm txheej siv tau yog raws li hauv qab no:
1. Lub zog sib piv
Titanium Alloy: Tensile zog ncav cuag 900-1100 MPa (piv txwv li, Gr5 titanium alloy), piv rau high-strength alloy steel, tab sis nws qhov ntom yog tsuas yog 60% ntawm cov hlau, uas ua rau muaj zog ntau dua (lub zog / ntom).
Stainless hlau: Common 316L stainless hlau muaj lub zog tensile ntawm kwv yees li 500-700 MPa. Thaum nws lub zog txaus, nws lub zog tshwj xeeb yog qis dua li ntawm titanium alloys.
Qhov txawv tseem ceeb: Titanium alloys yog qhov tsim nyog rau qhov hnyav -sensitive, siab - siv lub zog (xws li aerospace), thaum stainless hlau yog haum rau kev thauj khoom dav dav - cov kev cai bearing.
2. Corrosion Resistance
Titanium Alloy: Zoo heev corrosion kuj nyob rau hauv seawater thiab acidic / alkaline ib puag ncig. Nws cov yeeb yaj kiab oxide nto yog tus kheej - kho, thiab nws lub neej yog ob peb zaug ntawm stainless hlau.
Stainless hlau: 316L stainless hlau muaj corrosion kuj zoo, tab sis nws tseem yuav xeb nyob rau hauv siab - chlorine los yog muaj zog acid ib puag ncig.
Tej yam xwm txheej: Titanium alloys yog siv rau hauv marine engineering thiab chemical khoom; stainless hlau yog haum rau cov huab cua puag ncig.
3. Kub Adaptability
Titanium Alloy: Dav kub ntau (-196℃rau 550 degree), nrog zoo zog tuav ntawm qhov kub siab tshaj stainless hlau.
Stainless Hlau: 316L stainless hlau softens yooj yim tshaj 300℃thiab nthuav tawm qhov tseem ceeb brittleness ntawm qhov kub thiab txias.
4. Kev lag luam thiab kev siv
Tus nqi: Titanium alloy bolts tuaj yeem raug nqi 5-10 npaug ntau dua li cov hlau tsis muaj steel vim yog cov khoom siv siab dua thiab kev ua haujlwm nyuaj.
Siv Fields:
Titanium Alloy: Aerospace, kho mob cog, siab - tsheb sib tw kawg.
Stainless hlau: Kev tsim kho, khoom siv hauv tsev, kev siv tshuab dav dav.
5. Lwm yam yam ntxwv
Biocompatibility: Titanium alloy tsis yog - tshuaj lom thiab tsis yog - hlau nplaum, haum rau kev cog qoob loo kho mob; stainless hlau yuav ua rau muaj kev tsis haum.
Yooj yim ntawm kev txhim kho: Stainless hlau bolts yog yooj yim rau txheej txheem thiab zawm; titanium alloy bolts xav tau cov cuab yeej tshwj xeeb los tiv thaiv hnav.
